In the wake of the Motu Proprio Summorum Pontificum, which allowed for pastoral purposes celebration not only of the Mass but of the other sacraments, I have been asked a number of times by friars whether the Dominican Rite had its own particular forms for the sacraments. This is an interesting question, and I think readers here would find it interesting.
The Dominican Rite is a monastic rite and, as such, does not have forms for Baptism, Confirmation, Orders, or Matrimony. Dominican friars, like other religious, are assumed to be adults, and they are celibates, so there is no need for Baptism, Confirmation, or Matrimony. When they become bishops they canonically cease to be members of the Order, so Dominican bishops use the Roman rituals. If a friar is serving in a parish or other place where baptisms are performed, marriages witnessed, or an emergency Confirmation of an infant must be done, they would use the Roman rituals. We do have a form of the Missa Pro Sponsis in our missals, but its readings and collects are borrowed from the Roman Rite and it is a post-Tridentine addition. It is used with the customary forms for marriage.
Aside from the Mass, two sacraments were, and are, regularly performed in monasteries: Penance (Confession) and Extreme Unction (Anointing of the Sick). So the Dominican Rite has its own forms for those sacraments and these were also used in pastoral service to non-Dominicans. Both, like the Dominican Mass, represent ritual practice of the thirteenth century rather than the fifteenth- century usages codified in the Roman Rite after the Council of Trent.
Penance According to the Dominican Rite
The major external difference between the Roman and Dominican rites of Penance is in vesture. Roman priests traditionally heard confessions in cassock and surplice wearing a purple stole. Dominicans heard (and may still hear) confessions wearing the habit (which is white) and the cappa (the black cape), without a stole. The traditional explanation of the absence of the stole is that the scapular (a white apron-like part of the habit) is considered a stole. I think this story unlikely. The lack of church vestments in our rite is probably a vestige of the early medieval practice of using vestments only during administration of Public Penance on Holy Thursday. "Private" sacramental penance was not usually administered with external formalities at the time of the foundation of the Order. The black cappa was penitential enough.

The formula of Dominican Rite Penance is different in text and form from that of the traditional Roman Rite. As not all readers may be familiar with the older Roman form, I will describe it. In the modern period, both rites began with the penitent confessing his or her sins and then proceeded to the absolutions.
The Roman "Common Absolution" began with an invocation of God's mercy (Misereatur tui) similar to the priest's prayer in the modern Penitential Rite at Mass. He then raised his right hand and prayed a two-part absolution prayer. The first part invoked God's pardon, absolution, and remission of sins in the third person; the second part, the formal absolution, is in first person and first absolved the penitent from excommunication, suspension (if in orders), and interdict, and then from sins with a single Sign of the Cross. The priest then added the prayer Passio Domini Nostri, which remains an option in the new Rite of Reconciliation.
In the Dominican form, the priest began by absolving the penitent from excommunication, suspension (if a cleric), and interdict, explicitly stating that this restored the penitent to the communion of the faithful. Putting this first reflects the ancient practice that only those in full communion can pray with the faithful or receive ecclesiastical sacraments and rites. So it begins the rite as a whole. The Dominican priest then recited the Misereatur in a form identical to that used during the Dominican Prayers at the Foot of the Altar.
In thirteenth-century practice, this Misereatur prayer probably followed a ritual now absent from the rite. It was very common for priests to help penitents make confession by using a Formula Confessionis in question and answer form: "Did you take the Lord's name in vain?" "Did you commit adultery" etc. Priests can still do this today, if the penitent seems to have trouble identifying sins; and it is often used when a penitent makes a general confession. What today is relatively uncommon, seems, from my research, to have been nearly universal in the 1200s. After confessing their sins, penitents said a Confiteor (or some other formula of contrition) to which the priest added the Misereatur prayer, which normally followed it, as at Mass.
The priest then pronounced the Absolution. The Dominican form, in comparison to the Roman, because it lacks the absolution from censures, focuses more directly on sins and judgment. This is a remarkable prayer and incorporates not only the typical thirteenth-century focus on God's mercy, but also an explicitly eschatological dimension. Here is my translation of the Dominican formula:
May Our Lord Jesus Christ, the Son of the Living God, through his most gracious mercy, absolve you; and by his authority, through which I act, I absolve you of all your sins, so that you be absolved both here and before the tribunal of Our Lord, the same Jesus Christ, and so that you might have eternal life and live forever. In the name of the Father + and of the Son + and of the Holy + Spirit. Amen.
Here, for comparison, is the parallel prayer in the Roman Ritual:
May Our Lord Jesus Christ absolve you, and by his authority I absolve you from every bond of excommunication, suspension, and interdict, to the extent of my power and your need. Finally I absolve you from your sins in the name of the Father, and of the Son, + and of the Holy Spirit. Amen.
Note also the triple blessing in the Dominican form, something used in the Roman rite of Penance only by bishops. The Dominican, like the Roman, then concluded with the prayer Passio, which in the Dominican form mentions St. Dominic along with the Virgin, intentions as well as actions, and concludes with a final blessing in the name of the Trinity. Both the Dominican and Roman rituals provided shortened versions for use when penitents were many and a brief absolution for emergencies.
By analogy, in my opinion, as the use by Roman priests of older sacraments is now permitted for pastoral need, this form of absolution might be used by Dominican priests who have permission to use the Dominican Rite. I hope in another posting to discuss the Dominican form of Extreme Unction.
The Fra Angelico image of St. Dominic meditating at the beginning of this post could just as well show him seated to hear confessions: he is in habit and cappa and would be holding a "Formula Confessionis" or Manual of Penance on his lap as was typical in his time.
